Projects could be shut down and jobs lost unless a key transportation bill is renewed this month, according to US transportation secretary Norman Mineta. He is leading a nationwide campaign to urge Congress members to renew the Transportation Equity Act for the 21st Century (TEA-21) which is due to expire on 30 September. Delaying the passage of a full six-year plan could damage the economy and jeopardize the ability of state and local transportation leaders to plan and manage infrastructure projects, said Mineta.
